Focus on genetics

Preimplantation genetic screening (PGS) for aneuploidy (abnormal chromosome number) is available to women of advanced maternal age (35 years and above) with a history of IVF failure and/or recurrent miscarriage and other at risk couples. Follow-up analysis of abnormal embryos also provides valuable information about your chance of a live birth.

Currently we offer PGS for 7 chromosomes (out of 24 in total) frequently found in early embryos which result in miscarriage or abnormality. We will soon be expanding the number of chromosomes analysed and are developing new methods for 24 chromosome screening.
